![]() ![]() These keywords were added by machine and not by the authors. Based on the construction, we present a highly efficient attribute-based secret handshake scheme employing the CP-ABE scheme in. Specifically, we first present a generic construction of attribute-based secret handshakes from centralized ciphertext-policy attribute-based encryption (CP-ABE). In this paper, we propose the first efficient attribute-based secret handshake scheme which supports arbitrary matching policies with unlinkable and reusable credentials. introduced attribute-based secret handshake, in which a group member Alice can complete the handshake protocol with another group member Bob by specifying the attributes Bob must have. ![]() Secret handshake is an important building block of private communication over public networks, which allows two members of the same group to secretly authenticate each other and agree on a shared key for further communication. ![]()
